GALVANIC-BATTE RY CASE.

SPECIFICATION forming part of Letters Patent No. 227,865, dated May 18,1880.

Application filed March 18, 1880,

To all whom it may concern:

Beit known that I, J. HENRY C. WATTS, of Baltimore city, State ofMaryland, have invented certain new and useful Improvements in Electric-Battery Cases; and I here-by declare the same to be fully, clearly, andexactly the floor of the apartment in which the battery was placed.

I construct a casing adapted to tit the cell consisting of a metallicbody, A, having` a bead, a', and collar a, (which may be provided withan elastic washer,) and a cover, A', adapted to fit closely thereon.

A perforated bracket, B, is soldered to the (No model.)

casing, whereby the same may be secured by nails or screws to the wallat a convenient height. A gutta-percha or equivalent insulator-plate, C,is secured to the sideof the case, and is perforated for the passage ofthe wires c c from the cell D.

Being inclosed practically air-tight, the entrance of dust into the celland the efdorescence or deliquescence of its contents are prevented.Should the cell break, even, no particular harm is done, as it canreadily be replaced in the casing by a new jar. The insulator Cpreventsv the setting up of connection between the wires and incidentcutting out of the battery.

What I claim is- A casing for electric batteries consisting of themetallic body A and lid A', one of them being provided with theperforated insulatorplate D, as set forth.
